2 Claims.

The present invention pertains to a novel twin rolling armchair adapted to oscillate in a rectilinear movement.

The principal object of the invention is to provide an armchair of the character described in which the movement is initiated by the seated occupants.

Another object is to obtain a movement similar to that of a see-saw in that the motion transmitted to the device is of an ascending and descending nature. A further object is to produce an alternating rectilinear displacement which is doublethe movement impressed by the seated occupants.

Still another object is to provide a means for l maintaining the occupants in their respective positions without interfering with their functioning movements. Finally, a further object is to provide a device of this character which is secure'against accidents and which is recommended i'or persons having diiculty with their digestion.

It is well known that there exist suspended devices such as swings in which the seats are suspended in an overhead frame. In the present invention, the suspension is replaced by a rolling systembetween a base on the ground and a frame carrying the seats.

I' The armchairs `are fixed at each end in a frame which rests on rollers riding in turn on the aforementioned base. The rollers are embodied in a rolling floor, and a double lever is pivoted under the floor so that one end joins the base and the other end joins the frame of the chairs.

The invention is fully disclosed by way of example in the following description and in the accompanying drawings in which:

Figure l is an elevation of the device, partly in section;

Figure 2 is a section on the line 2 2 of Figure l;

Figure 3 is a transverse section at the center; and

Figure 4 is a detail transverse section.

Reference to these views will now be made by use of like characters which are employed to designate corresponding parts throughout.

The base I of the device is simply a rectangular frame resting on the ground 2. The base is formed of timbers wide enough to provide a rolling surface for four rollers 3 joined in pairs at each end by two transverse shafts A'. The rollers are preferably provided with a ange 5 lat the inner side, and flat metal rails rest on the upper surface of the base I to provide a better traction surface for the rollers and also to protect the base from wear.

The shafts 4 traverse the ends of two longitudinal members or rails I adjacent to the alined rollers, and the rails I are joined by parallel transverse slats 8 spaced equally apart and constituting Aa rolling floor. On the rollers 3 is mounted a, frame 9 having the same dimensions as the base I. More exactly, the bottom surface of the frame 9 is formed with curved notches Ii) (Figure l) at the inner edge. The horizontal surface of the notch is lined with a metal strip I I to reduce wear.

The frame 9 carries at each end an armchair of the so-called Laurentian or Adirondack style, nailed, screwed or bolted in position. The forward legs I2 thereof are vertical and are joined directly to the sloping rear legs I3 which support the seat I4. The horizontal arms I5 are secured at one end upon the forward legs I2 and at the other end to a transverse bar I6 on the inclined back I1.

Finally, at the center and on the bottom of the rolling floor 8 is fixed a block I8 to which is pivoted at I9 the midpoint of a transverse lever 2B. The ends of the lever are forked to slidably receive a, pin 2I in the bottom of the frame 9 and another pin 22 xed upon the base I, as clearly shown in Figure 3. For the protection of the occupants, the spa-ce between the frame 9 and the base l parallel to the rails I is covered by boards 23 suspended from each side of the frame 9. Between the rolling door 8 and the ends of the base I, the latter carries a grille 24 formed of parallel slats secured at their ends to the ends of the base structure.

In the use of the device, the occupants seated in the chairs merely exert slight foot pressure on the rolling floor 8. The rollers 3 thus ride on the base I and the frame 9` is displaced twice as far as the floor 8. The displacement of the armchairs is twice as much as in prior devices. The same action occurs in both directions. Because -of the curvature of the notches It, the movement has ascending and descending components resembling the motion of a swing or see-saw. Uniform motion is assured by the balancing of the lever 20, without interfering with the longitudinal motion. Excessive travel is prevented by the outer ends of the notches I0 which are rather abrupt, so that the momentum changes the direction and thus introduces the rectilinear oscillation. A stop 30 on the frame l is also used for limiting the travel of rollers 3.

Although a specific embodiment of the inven- 3 tion has been illustrated and described, it Will be understood that various alterations in the details of construction may be made without departing from the scope of the invention as indicated by the appended claims.

What I claim is:

1. In combination, a base, a floor, rollers carried by said floor land riding on said base, a frame loosely enclosing said floor and resting on said rollers, and a pair of chairs mounted on the ends of said frame and crossing said floor, and a lever pivoted centrally to the underside of said floor and having its ends attached respectively to the bottom of said frame and to the top of said base.

2. In combination, a base, a floor, rollers carried by said floor and riding on said base, a frame loosely enclosing said floor and resting on said rollers, and a pair of chairs mounted on the ends of said frame and crossing said oor, said frame having curved notches receiving said rollers, whereby the frame is given an ascending and descending motion While oscillating horizontally, and a lever pivoted centrally to the underside of said iioor and having its ends attached respectively to the bottom of said frame and to the top of said base.
